Regarded as an effective method for identifying drug and alcohol consumption, hair testing offers significant advantages. The strands of hair capture biomarkers, providing an extended record of alcohol and drug intake. A sample trimmed near the scalp reveals usage history for approximately three months. Collecting hair is straightforward, hard to falsify, and simple to transport.
A 1.5-inch section comprising around 200 hair strands (resembles a #2 pencil thickness) near the scalp yields 100mg, the recommended sample size for testing and verification. For EtG, supplementary tests, or beyond ten panels, a sample of 150mg is suggested. It's advisable to measure the sample on a jeweler’s scale. If scalp hair isn't available, equivalent body hair can be considered. "Head hair" specifically means scalp hair, while "body hair" encompasses all other body hair types (like facial or axillary hair).
Process Overview
The laboratory processing of a drug test outcome consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially introduced into a laboratory’s system—ensuring the sample's proper sealing and transport, assigning a LAN (Laboratory Accessioning Number), and completing any additional data entry not included in an electronic chain of custody.
Screening is a preliminary and swift process to check for drug abuse. It serves as a cost-efficient method to exclude drug usage in most samples. However, positive results in Screening necessitate confirmation for legal admissibility. Any sample showing presumptive positive outcomes during Screening requires subsequent confirmation.
For samples indicated as presumptively positive during Screening, additional hair from the initial sample is prepared for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than other methods (e.g., urine or oral fluids), making hair drug screening the most complex procedure.
Confirmation of any positive outcomes is accomplished using GC/MS, GC/MS/MS or LC/MS/MS techniques. Before confirmation, all presumptive positive samples undergo washing as needed. The full laboratory process from Accessioning to Confirmation is audited under the College of American Pathologists (CAP) Hair designation and adheres to ISO / IEC 17025 standards.
